问题 I need to highlight single words or phrases matching the $key (whole words, not substrings) in an UTF-8 $text. Such match has to be both case-insensitive and diacritic-insensitive. The highlighted text must remain as it was (including uppercase/lowercase characters and diacritical marks, if present). The following expression achieved half the goal: $text = preg_replace( "/\b($key)\b/i", '<div class="highlight">$1</div>', $text ); It's case insensitive and matches whole words but won't
